So .. i got this turbo the size of my head , and i dont want to buy the wrong parts .. i got the turbo / rb25 intake manifold from greddy / greddy front mount intercooler / q45 throttle body /850 injectors / apexi fc commander/.. what else do i need for the let me know im aiming at 500 horse power / getting cams and bore/ pistons later.
the specs are .58 ar 1.11 (T4 flange) i think .. the closest i could find info about it is that its a Gt37 to Gt40 ~ let me know what u guys know ..Now for pics.

You'll need a new exhaust manifold. That won't fit on the stock T3 flange unless you plan to use some kind of adapter plate.

thought that was obvious.. i dont think that would fit in stock location with an adapter plate..
